PATENT ARTHUR GRAHAM GLASGOW, OF LONDON EN GLAND, ASSIGNOR TO HIM- SELF,AND ALEXANDER O. I-IUMPI-IREYS, OF NEXV YORK, N. Y

FEED-WATER HEATER FOR GAS-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 586,968, dated July 27,1897. Application filed October 16, 1896. Serial No. 609,052x (Nomodel.)

To all whom it may concern.-

Be itknown that I, ARTHUR GRAHAM GLAS- GOW, a citizen of the UnitedStates, residing in London, in the county of Middlesex, England, haveinvented a certain new and useful Improvement in Feed-Water Heaters for-Gas-MakingApparatus, of which the follow feed-water of the boiler.

In the manufacture of gas for general distribution it is the usualpractice to cool the newly-manufactured gases down to about 60Fahrenheit before passing them to the holder or mains, and this coolingis not infrequently eifected in surface condensers, the hot water comingfrom which is allowed to run to waste or is cooled for reuse, and theprincipal object of my invention is to utilize this hot water asfeed-water for the boiler.

It will be obvious that no fixed relation exists or could exist betweenthe quantity of water required to feed the boiler and that needed forcooling thegas. Indeed, the quantity of water required for each purposewill very frequently vary, and vary not infrequently in inverse relationthe one to the other; and my invention consists in meeting thiscondition of use by providing a well or receptacle to receive the hotwater from the surface condenser and to serve as the feedwater reservoirfor the boiler, and in providing this well, in addition to itsconnections, with the condenser and the boiler with a wastewateroverflow by which the water contained in it can escape when it exceeds adetermined 1 height, and with a supplemental water-supply pipe providedwith a valve which is opened or closed in accordance with the level ofwater in the well and by which any deficiency in the supply of watercoming from the condenser can be made up.

Reference being now had to the drawing, which illustrates my inventionas applied to a water-gas apparatus of familiar type, and in which A isa generator having gas takeoff pipes B and B leading from its bottom andtop, I? and 1) indicating valves in these takeoff pipes, both of which,the pipe B directly and the pipe B through pipeB connects with a singlepipe B whichleads into the top of the carbureting-chamber C, from whichthe gases pass through pipe D into the bottom of the fixing-chamber E,whence the blast-gases escape through pipe F into the stack G, and whenwater-gas is being made it passes through pipe H to the washer I, thencethrough seal-box J and pipe K to the scrubber L, and thence through pipeM through the surface condenser N, from which it passes through pipe 0to the necessary apparatus, receiver, and mains. The surface condenser Nis of usual construction, having at each end of the portion throughwhich the gases pass heads M and M these heads being connected bywater-pipes M passing from the water-receiving chamber N to the waterdelivery chamber Nflwhich, in the construction shown, serves as the wellor receptacle from which the boiler draws its feedwater.'

0 indicates the supply-pipe, through which water is forced into thecondenser.

P is the overflow-pipe, by which water can escape from the well N whenit exceeds a determined height.

Q is an auxiliary or supplemental supplypipe leading into the well N andhaving a cook or valve Q, opened or closed by the float Q in accordancewith the height of Water in the well N R is thefeed-water-supplypipe,which leads to the boiler T, S being a feed-waterpump, and the portion of the supply-pipe leading from the pump to theboiler being marked R.

T indicates a steam-pipe leading from the boilerand connecting throughbranches T and T with the pipes B and B, A indicating a valve by whichthe steam can be directed into either branch T or T or out off from bothat will.

U indicates the air-blast-supply pipe, and U, U and U branches thereofleading to the various parts of the apparatus where air is from time totime required.

The gases generated in the generator A, after passing through thecarbureting and fixing 0r superheatin g chambers and through the washerand scrubber, pass through the surface condenser N and are cooled by thewater forced upward through the pipes N the heated water from thesepipes passing into the well N which is conveniently placed, as shown,upon the top of the carbureter, but may, if desired, be in any otherposition. From this well the pump S constantly draws feed-water for theboiler through the pipe R, and in case the supply of water to the boileris excessive the excess escapes through pipe P, while ii. the supplyfrom the condenser is not sufficient to feed the boiler the falling ofthe water in well N will throw the action of the float Q upon the cock Qand permit additional water to flow from pipe Q into the well until thenormal height of water is secured therein.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with a gas-making apparatus and a steam-boiler a surfacecondenser forming a part of the conduit through which the hot gases passafter leaving the gas-making apparatus, a well or receptacle as N"arranged to receive the water passed through the condenser for thepurpose of cooling the gases, a supplemental water-supply pipe as Qopening into said well, a cook or Valve Q situated in said pipe Q andcontrolled by the water-level in the well, an overflow as 1 arranged topermit the escape of water from the well when it reaches a determinedheight therein, a feed-water pipe as R leading from well N to the boilerand means as pump S for forcing the heated water into the boiler.
